Ensure non-Apple GPU's enable memory barriers.
A previous commit inadvertently disabled GPU memory barriers.
Change tests for memory barriers to runtime test for Apple GPU, instead of
build-time test for Apple Silicon, to accommodate running on Rosetta2, and
refactor tests for Apple Silicon and OS version on some macOS GPU feature settings.
For a combined depth-stencil format in a MVKImageView attachment with
VK_IMAGE_ASPECT_STENCIL_BIT, the attachment format may have been swizzled
to a stencil-only format. In this case, we want to guard against an attempt
to store the non-existent depth component.
Pass MVKImageView attachment to MVKRenderPassAttachment::encodeStoreAction()
and MVKRenderPassAttachment::populateMTLRenderPassAttachmentDescriptor() to
check attachment depth format component.
Consolidate calls to MVKImageView::populateMTLRenderPassAttachmentDescriptor() by calling
it from within MVKRenderPassAttachment::populateMTLRenderPassAttachmentDescriptor().
When flattening shader inputs for stage_in, which are to be read from a buffer
that was populated as nested structs during an earlier stage, the structs will
be aligned according to C++ rules, which can affect the alignment of the first
member of the flattened input struct.
Add SPIRVShaderOutput::firstStructMemberAlignment to track the alignment
requirements of the first member of a nested structure, and recursively
determine the alignment of the first member of each nested output structure.
Move sizeOfOutput() from MVKPipeline.mm to SPIRVReflection.h,
rename to getShaderOutputSize(), and add getShaderOutputAlignment()
to extract member alignment.
mvk::getShaderOutputs() in SPRIVReflection.h support flattening nested structures.
MoltenVKShaderConverter tool support loading tessellation shader files.
MoltenVKShaderConverter tool update to MSL 2.4 by default.
Remove use of deprecated MTLCreateSystemDefaultDevice().
Update to latest version of SPIRV-Cross.
If using GPU counters, on all Apple GPUs lock timestampPeriod to 1.0,
since Apple GPUs use nanoseconds, and on non-Apple GPUs, dynamically
adapt value of timestampPeriod by correlating GPU ticks with GPU ticks.
If using CPU sync, set timestampPeriod to OS CPU timestamp tick period.
Previously, on Apple Silicon (iOS, tvOS & macOS M1), we tried to guess
deviceID from GPU parameters, but this is becoming harder as the types
of Apple Silicon is growing, and the actual device SoC itself is less
relevant that the GPU capabilities. So we now set deviceID from the
combination of OS version and GPU type.
Rename MVKDevice::getHighestMTLFeatureSet() to getHighestGPUCapability().
Older Metal does not support rendering without subpass attachments.
In this case, a dummy attachment with a dummy MTLTexture is created
whenever the subpass begins, but was not being correctly used.
Move the creation, retaining, and releasing of the dummy MTLTexture to
MVKFramebuffer, where the extent and layer count is known and can be reused.
Pass framebuffer to MVKCommandEncoder::beginRenderpass() and remember
current framebuffer in MVKCommandEncoder.
Add getFramebufferExtent() and getFramebufferLayerCount() to MVKCommandEncoder.
Pass framebuffer to MVKRenderSubpass:populateMTLRenderPassDescriptor() and
retrieve dummy MTLTexture from framebuffer.
Move the aliasing of promoted function pointers to the function pointer
lookup collection, because non-global function alias symbols are not
available in separately compiled object file.
Add public aliased Vulkan extension functions that were promoted to 1.1 to
the public symbols that are hidden when MVK_HIDE_VULKAN_SYMBOLS is enabled.
Add functions from the private VK_MVK_moltenvk extension that depend on
Vulkan object handles to the public symbols that are hidden when
MVK_HIDE_VULKAN_SYMBOLS is enabled, to discourage their use by apps that
are using the Vulkan Loader and Layers, because they are not supported by
the Vulkan Loader and Layers.
Update VK_MVK_MOLTENVK_SPEC_VERSION to version 33.
Do not use MTLEvent for VkSemaphore under Rosetta2.
Remove compile test for MVK_MACOS_APPLE_SILICON and MVK_APPLE_SILICON when testing
for Apple GPU families, to allow x86 builds to test for Apple GPU under Rosetta2.
Simplify identifying M1 GPU. All M1 SoCs currently support the A14 (Apple7) GPU.
Support compiling MSL 2.4 in runtime pipelines and MoltenVKShaderConverterTool.
Fix issue where MSL 2.3 only available on Apple Silicon, even on macOS.
Update to latest SPIRV-Cross (unrelated to Rosetta2).
Add build environment variable MVK_HIDE_VULKAN_SYMBOLS. to allow MoltenVK
to be built with static Vulkan API symbols hidden, to avoid library linking
conflicts when bound to a Vulkan Loader that also exports identical symbols.
The default value of MVK_HIDE_VULKAN_SYMBOLS is 0,
meaning Vulkan static symbols are exposed by default.
Add MVK_PUBLIC_VULKAN_SYMBOL directive to mark each Vulkan call symbols
for exporting or hiding.
Update the MoltenVK Xcode project to add the MVK_HIDE_VULKAN_SYMBOLS build
setting, and set the ENABLE_TESTABILITY build setting to NO, because it
conflicts with stripping symbols.
Update MoltenVK version to 1.1.7.
